`citizen of they GermanEmpire,` residing at Berlin, Germany, havey invented certain new -andjuseful Improvements' in Wooden Cigal retteCas'es (for which Il'iavefiled applica'- tions in GermanyMarch 19, 1919,Patent No.f4-325,659, September l5," '1920, and in England, July 6, V1920), of which thefollowing is a specification.

My invention refers to cigarette cases and j between the hinge tongues of the body of more especially to cigarette cases made en tirely of wood and known generally as Russian cigarette cases. Up till now these cases were carved wholly by hand. The endeav! curs made up till now to produce such cases by machine, all failed without exception. Though it was possible to work the body and the lid of the case with machines, the atj tempts to manufacture the hinge connecting the lid and the body of the case with the aid of machines remained unsuccessful. The reason for these failures lay in the fact that the hinge parts of the body of the case as well as of the lid have cylindrical shape or form parts of a cylinder respectively, in

vorder to make the hinge parts fit into one another tightly; consequently it is necessary to determine the curvature of the curved edges between the various tongues of the hinge by a circle the centre of which is lovcated within the hinge-pin journal.

Consequently the milling cutters must be extremely small, if machine manufacture is intended; in point of fact the diameter of the milling cutters must correspond approximately to that of the tongues of the hinge, which fact makes it perfectly obvious that such milling cutters cannot be employed. Even with thecigarette cases made by mflachine up till now it was therefore necessary to resort to manual labour,'if only for working the hinges, this, however, increasing the costs of production so considerably that such cigarette cases proved a commercial failure.

My invention does away with the drawbacks mentioned by shaping the hinge in such a way as to allowv of working the hinge by machine, whilst still maintaining a tight lit. The characteristic feature of my invention consists in the curved edges situated between the hinge tongues of the body of the case and of the lid forming part of a circle the centre of which; is located outside the hinge-pin journal. Consequently it is permissible to,r` employ larger milling 'cutters whose 'centres cfrot'ation lcan' have a. positionl outside the -section ofthe hinge lpin and whichcan be therefore be employed satisfactorily'xfor performing work, lon'the hinge. In order to )prevent the tobacco y frequently dropping from'cigarettes andA collecting' in the case fronfpen'etrating Ainto the yhinge ev'en when thecigarette case is open" (a regu lar occurrence ywith the cigarette cases as made hitherto) the bent edges existing the case, form the exterior surface of a wall or rib provided in the bodyof the case on the side fitted with the hinge, the said wall or rib protecting the hinge against the entrance of tobacco dust. v

In the drawings aiiiXed to this specifica# tion and forming part thereof a cigarette case embodying my invention, is illustrated by way of example. ln'the drawings.

Fig. 5 is a section of the body proper -of the case, and

Fig. 6 is a section of the lid proper,

Referring to the drawings, l is the body and 2 is thelid as usual. rllhe body l as well as the lid 2 is provided with eXtensions 3 and 4 respectively which are delimited by two curved surfaces of varying radii, the holes 7 serving to receive the hinge-pin journal being arranged eccentrically in the said extensions. Moreover the curved edges 8 between the extensions 3 and 4 are determined by a circle the centre of which is situated outside the hinge-pin journal.

As will be noticed especially in Fig. 4 tight closing of the hinge is achieved in spite of the differing formation of the component parts of the hinge.

In order to prevent the tobacco dust which frequently collects in the body of the case from the cigarettes contained in it, from penetrating in between the component parts of the hinge, a wall or rib 9 is pro- This rib prevents the tobacco dust from slippingin between/the component partsof the hinge, es Will-"be observed-Ain Fi'gsfl and', the hinge therefore permanently i'emeining in good Working condition.
